vices of the well-known unitswitch type and the like.

The object of our'mventlon is to provlde a device of the above-indicated character which may be mounted in any convenient location and which shall embody a plurality of stationary frame members and hinged cover members collectively adapted to form a suitable number of separate apparatuscontaining compartments. I

The total. cost of manufacturing and installing such a device, the weight of the ap.

paratus and the space required underneath.

a railway vehicle are materially reduced, and the accessibility of the apparatus after installation is greatly increased.

Our invention is characterized by a compact, rugged rectangular unitary structure which is relatively light in weight and which may be readily installed, inspected and repaired. Moreover, the compartments on opposite sides of each end-plate are su'bstantially gas tight, thereby being adapted to prevent the passage of conducting vapors between the various pieces of apparatus.

In the accompanying drawings, Figures 1, 2 and 3 are views in plan, in side elevation and in end elevation, respectively, of a switch group constructed in accordance with our invention; and Figs. 4:, 5 and 6 are views in plan, in side elevation and in end elevation, respectively, of a modified form of switch group embodying our invention.

Referring to Figs. 1, 2 and 3 of the drawings, the structure shown comprises a switch group provided with a suitable supporting frame 1 of customary construction that is provided, at its respective ends, with a plurality of end plates 2 and 3, which, respectively, have integrally connected topcover members Q and 3 of substantially the Same width as the body portion of the switch group and through which a plurality of condrictor-receiving openings 2" and 3"and supporting bolt-receiving openings 2 and 3 respectively extend. A plurality of complementary right-angled, suitably internally insulated cover members l are hinged to the body portion of the switch a group at the points a on each end of the group and are adapted to be fastened together to form suitable end compartments, as hereinafter described, by means of appropriate latch members Al A plurality of cover members 5,.which are adapted to inclose the sides of-the body portion ofthe switch groupi, are suitably removably associated withthe supporting frame member 1 at thepoints 5 andare' secured together by meansof one or more latches 5 The sets cfcovermembers tand 5 are thus eaclrcentrally divided in a plane normal] to-the end-plates, which makes for ready accessibility; to the interior of the casing. Each cover member 4: comprisesthree walls severally disposed I normally to the other walls,-while each cover member 5 embodies two right-angled walls. Thus, distinct and completely-inclosed compartments for the reception of any desired control apparatus are provided.

Referring now to the modified structure illustrated in the remaining figures; Figs. *1, 5 and 6 show a switch group comprising a suitable supporting frame 18 that is provided with side openings through which main-circuit conductors 19 are adapted to pass; a plurality of end plates 20 and 21, for the respective ends of the frame 18, that are respectively provided with suitable integral tOP-COVGr members 20 and 21*; a plurality of right-angled cover members 22, similar to those described in connection with Figs. 1 and 2-, which are suitably hinged upon the body portion of the switch group at points 22 and may be suitably centrally secured together by means of latches 22*; a plurality of similar cover members 23, for the other end plate 2-1, which are suitably hingedto the body portion of the switch group at the points 23* and may be fastened together by means of suitable latches 23 a plurality of side-cover members 24.- which may be hinge-secured to the frame member 18 at therpoints-25; and an arcing box ABcomprising a plurality of arcing chutes AG for'certain of the unit switcheseomprised within the body portion of the switch group? The switch group,

as a whole, may be supported, by means of ch'annel'irons 26, upon the underside of a railway vehicle floor 27, or it may be supported in any other well-known manner.

In the control apparatus hereinbefore described, We have provided a switch group comprising a pair of end plates, and a pluspecific structural details or arrangement of parts'herein set forth, but desire that only such limitations shall be imposed as are indicated in the appended claims.

lveclaim as ,ourinvention: I

1. A'eas'ing comprising a frame, a plurality of end plates secured to the frame, side cover members. hinged to the frame and adapted to inclose the bottom and sides of the space between said end plates, and cover members hinged to the said end plates and adapted to form distinct compartments therewith.

2.1x easmg comprising a frame, an end member secured thereto and having an out- 40 wardly extending top portion normal to the .main portion thereof, and a' two-part cover member divided in a plane normal to both portions of the said end member and adapb ed to form a distinct compartment there with, said cover members being hinged to the main portion of the said end member.

3. A casing compr1s1ng a frame, a plurality of end plates secured to the frame and provided with outwardly extending top portions, a cover adapted to fit between the end plates and below the frame, a cover adapted to fit between the end plates and above the frame, and a cover adapted to cooperate with one of the end plates to provide a distinct compartment.

I t. A casing comprising a frame, end plates secured to the said frame, complementary cover members hinged to the frame and divided in a plane centrally normal to the 6 end plates, complementary cover members hinged to the said end plates and divided in the said normal plane.

In testimony whereof we have hereunto subscribed our names this 9th day of Oct,
